## Description

desertcart.com : LastiSeal Brick & Concrete Sealer Satin (5-gal) - Water-Based Penetrating Sealer for Brick, Concrete, Stone, & Porous Masonry - 15-Year Waterproofing Warranty, Low Gloss Sheen : Tools & Home Improvement

Review: Product works advertised... Great Satin Finish. - I applied this product on 120 year old interior (red) brick walls. All brick and mortar surfaces were washed with water and allowed to dry completely prior to application. Some walls were previously skim coated with plaster and painted. These walls had to be power sanded with 40 grit and then acid washed. I used a 3 inch brush to liberally apply the product to the brick and mortar. Then I allowed it to soak in for about 5 minutes before brushing out any runs. Some bricks soaked up the sealer very quickly and required an immediate second coat. There's no rushing this process, but it has been worth the effort to me.
Review: Great product. - I used this on two old brick chimneys that are almost 100 years old. Stopped the leak through.

## Features

- Long-Lasting Protection: Deep-acting concrete and brick sealer provides up to 15 years of protection while helping reduce water absorption, weathering, and surface wear. Leaves a subtle satin (low-gloss) finish without forming a heavy coating.
- Satin Finish: Provides a subtle, low-gloss finish that enhances the natural texture and color of brick, concrete, and pavers.
- All-Weather Protection: Helps protect concrete, brick, pavers, mortar, and porous stone from rain, snow, road salts, and freeze-thaw cycles. Surfaces dry fast, reducing cracking, spalling, and long-term weather damage.
- Reduces Efflorescence: Helps reduce water absorption to minimize efflorescence, protecting masonry surfaces from staining, residue buildup, and surface deterioration.
- Advanced Water-Based Formula: Unique blend of polyester, polyurethane, and acrylic polymers creates a durable, breathable masonry sealer that works below the surface to strengthen and protect without trapping moisture.
- Hardens & Strengthens: Helps reduce surface dusting and harden soft mortar joints while reinforcing porous concrete, brick (including historic Chicago brick), sandstone, and mortar, improving durability and reducing surface wear.
- Versatile Indoor & Outdoor Use: Use on chimneys, driveways, pool decks, patios, garage floors, retaining walls, and fireplaces. Ideal for a wide range of interior and exterior porous masonry surfaces

## Questions & Answers

**Q: Does the satin provide any color enhancement or would I need an additional product for that?**
A: I have only used it on brick and the satin does not change the color so you need an enhancer.  I would think another product might be better as some enhancers are sealers as as well.

**Q: What can I use to seal painted brick?**
A: You should see if you can repaint with elastomeric paint. It is plastic, but allows the bricks to breath. It forms a hard shell.

**Q: It says it is penetrating water-based sealer, but yet it is a polymer.  Can you reseal over the top of this product after time has gone by?**
A: yes, as long as you give the surface a good deep cleaning.

**Q: I don't want a sheen on the pavers & need to enhance them. Can I use the Satin sealer first and then come back with a second coat of the flat sealer?**
A: If you do not want a sheen, use LastiSeal Flat. Do not apply more LastiSeal to a surface that has already been sealed with LastiSeal, Flat or Satin.
